I will not upgrade to PostgreSQL 7.2 before pgAdmin I development features
are ported, one way or another, to pgAdmin II.

I don't agree. logfiles do not always represent the actual chronological
sequence of object development.
Again any application, i.e. phpPgAdmin, should be able to write in pgAdmin
development tables.
Looking for dependencies in the source code is much more relevant and
consistent.
Then you compile code and review compilation errors.

No, it not safer. If you run a DROP FUNCTION query in psql, you might not
notice it before publishing.
I will never believe that storing source code in two different places
(PostgreSQL and revision logs)
is better than in one place development tables. This is a problem of
consistency.
Using development tables, anything can be organized within one transaction.
In the long run, we could also write PL/pgSQL triggers to compile code
interactively!!!
It will never be the case with revision logs.

Well, we are discussing about two different issues:
1) keeping source code in development tables better <-> retrieving source
code from logs in case of problems.
2) compilation in dependency order (=publishing, I think it is close).
We agree on 2) and disagree on 1).
